IMPROVEMENT'IN TOOL, POR'DRIVING- GLAZIERSPOIN' I'S.

The Schedule referred to in these Letters Patent and making part at the same.

To all whom it may concern.-

Be it known that we, ALFRED WoonwoRrH and Eovvm Warmest, of Cambridge, in the county of W aslnngton and State of New York, have invented a new arid vimproved Tool for Driving Glaziers Points; and we do hereby declare that the following is a full,,clear', and exact description thereof, which will enable others skilled in the art to rnakeand use the same, reference being bad to .the accompanying drawing tbrming part of this specification.

This invention relates to improvements in machines or tools for driving glaziers points, and consists in a hand-tool having a vertical receptacle for the points, and a spring driver, arranged to strike the lowest point in the receptacle,'and force it out through aslot thereat, the-said spring driver being provided with a retracting pawl, which trips the driver and re-cngages gitllii it self-actingly,.allas hereinafter more frilly Spec- 1 e Figure 1 is a sectional elevation of my improved tool, and

Figure 2 is a horizontal section of the same.

A is the stock, 4

B, the handle, and

G, the base of the-tool, preferably made of metat, or it may be partly of metal and partly of wood, and either in parts attached together, or all cast or otherwise formed in one piece, as preferred.

D is a vertical triangular chamber for the points, at

the-frontof the bottom of which is a horizontal slot,

E, wide enough to allow one point to be forced out, and behind the chamber, at this, point, is a thin dr'rver, F, preferably of steel, attached to ablock, G, having a long red, H, extending rearward in an extensioml, of the stock, for the application. of a strong spiral spring, K, for driving the driver F against the points.

L is a pawl for forcing the block (iback against the spring K.

It has ahandie, M, arranged under the handle 13,-,

so as to be taken conveniently in hand, while holding the tool to raise it and forcethc spring back.

The lower end of the pawl L carries a spring catching and tripping-pin N ina socket, O, in which is a coiled spring, P, which presses the pin down upon the block G.

This block has-a shoulder, Q, in front of which the spring catch falls when the handle M is pressed down, and on which it acts-to force the drum back whenthe handle M is raised.

The raising of the handle swings the pawl on the pivot R, so as to raise the catch-pin above the shoulder Q when the driver has been forced back far enough, and the spring K then throws the driver forward against the lowest point in the chamber D, with suificient. force to drive it into the sash.

The pawl L is forced back again by a spring, S, bearing against the top of it, and, as soon as the lower end comes forward again, the catch N dropsin front of the shoulder Q, ready for the next operation.

The wall X of the chamber is made detachable, for supplying the points more readily, the said wall being taken off for the purpose. It is held in place by the lugs 3 on the other wall, and the button Z, pivoted to the side of the case by the screw Z.

T is a follower, placed in the chamber above the points to force them down, and it is operated by an elastic cord, U, wound on a small roller, V, in a recess in the upper part of thetool-stock.

The front end of the base-plate G is made thin-l her than the other, so that the points will be driven close down upon the glass when the tool is set thereon. The rear end of the base may also be raised by anotherplate, W, forthe same purposes. By changing the shape of the chamber to adapt it to other articles, and also changing the form of the driver, nails, brads, pins, or other similar things'may be driven by the same apparatus.

Having thus described our invention,

We claim as newand desire ,to secure by Letters Patent-i The combination on. stock A, provided with a chamber, D, of a spring-actuated driver, F G, retractingus this 1st day of 'April, 1870.
